Hello.
I have more problems with my Geeetech alu prsa 3d printer.
I do not know how to change the direction of the engine on the Z-rod. I do not know how to teach firmer Marlin-Arduino as described in the forum. I managed to turn the wire switches so now the engines go in the right direction.
Printer prints PLA PRO wire, edges are very rough. The ABS wire comes out for 5 seconds and then goes out of the nozzle.
tnx for help

The temperature of ABS is 230-270 and the bed is 95C
If you don't know how to change the direction of the motor, you can upload the configuration.h file to google drive.
I will help you in my spare time.
